Be_ Ope_t_n

1. Contact an installation specialist for installation.

This is NOT a do-it-yourself project.

2. Plug in the power plug properly.

3. Use a dedicated circuit.

4. Do not use an extension cord. Consult a professional installer or electrician.

5. Do not start/stop operation by plugging/unplugging the power cord.

6. If the cord/plug is damaged, replace it with only an authorized replacement

part.

1. Being exposed to direct airflow for an extended period of time could be

hazardous to your health. Do not expose occupants, pets, or plants to direct

airflow for extended periods of time. In other words, don't sit in the draft.

2. Due to the possibility of oxygen deficiency, ventilate the room when used

together with stoves or other heating devices.

3. Do not use this air conditioner for non-specified special purposes (e.g.

preserving precision devices, food, pets, plants, and art objects). Such usage

could damage the items.

1. Do not touch the metal parts of the unit when removing the filter. Injuries can

occur when handling sharp metal edges.

2. Do not use water to clean inside the air conditioner. Exposure to water can

destroy the insulation, leading to possible electric shock.

3. When cleaning the unit, first make sure that the power and breaker are turned

off. The fan rotates at a very high speed during operation. There is a

possibility of injury if the unit's power is accidentally triggered on while

cleaning inner parts of the unit.

For repair and maintenance, contact your authorized service dealer.

Owner's Manual 9

Electrical Safety

IMPORTANT

(PLEASE READ CAREFULLY)

FOR THE USER'S PERSONAL SAFETY, THIS

APPLIANCE MUST BE PROPERLY GROUNDED

The power cord of this appliance is equipped with a

three-prong (grounding) plug. Use this with a standard

three-slot (grounding) wall power outlet to minimize the

hazard of electric shock. The customer should have

the wall receptacle and circuit checked by a qualified

electrician to make sure the receptacle is properly

grounded.

DO NOT CUT OR REMOVE THE THIRD (GROUND)

PRONG FROM THE POWER PLUG.

A. SITUATIONS WHEN THE APPLIANCE WILL BE

DISCONNECTED OCCASIONALLY

Because of potential safety hazards, we strongly

discourage the use of an adapter plug. However, if you

wish to use an adapter, a TEMPORARY

CONNECTION may be made. Use UL-listed adapter,

available from most local hardware stores.

The large slot in the adapter must be aligned with the

large slot in the receptacle to assure a proper polarity

connection.

Ak CAUTION

Attaching the adapter ground terminal to the wall

receptacle cover screw does not ground the

appliance unless the cover screw is metal, and not

insulated, and the wall receptacle is grounded

through the house wiring. The customer should have

the circuit checked by a qualified electrician to make

sure the receptacle is properly grounded.

Disconnect the power cord from the adapter, using

one hand on each. Otherwise, the adapter ground

terminal might break. DO NOT USE the appliance with

a broken adapter plug.

B. SITUATIONS WHEN THE APPLIANCE WILL BE

DISCONNECTED OFTEN

Do not use an adapter plug in these situations.

Unplugging the power cord frequently can lead to an

eventual breakage of the ground terminal. The wall

power outlet should be replaced by a three-slot

(grounding) outlet instead.

USE OF EXTENSION CORDS

Because of potential safety hazards, we strongly

discourage the use of an extension cord. However, if

you wish to use an extension cord, use a CSA

certified/UL-listed 3-wire (grounding) extension cord.

10 Room Air Conditioner

CAUTION

Installation

• There are sharp edges that can cause serious cuts.

• If the unit is to be installed close to the seaside, itneeds

additional treatment on the heat exchanger.

• When lifting the air conditioner, it is HEAVY.

Use 2 people to lift.

Dimension of air conditioner

1,066 mm

For existing sleeve, you should measure the wall sleeve

dimensions.

You can install the new airconditioner according to these

installation instructions to achieve the best performence. All

wall sleevesused to mount the newair conditioner must be

in good structural condition and havethe rear grille that

securely attaches to the sleeve or the flange of the sleeve

to secure the new air conditioner.

• To avoid vibration and noise, make sure the unit is

installed securely and firmly.

When installing the sleeve, make certain there is nothing

within 20" of the back that would interferewith heat

radiation and exhaust air flow.

Dimension of sleeve assembly (optional)

A CAUTION

• Before installation, Check the insulation on the inner side

of the sleeve. Ifthere is no insulation, place the insulation.

• Check the bottom corner's joint gap of the sleeve, If there

is, fill the gap with putty.

IfTt_'7/_ To maintain the best

performance of the LG PTAC,

an insulation strip must be

attached. The insulation strip

is provided with the box.

Refer to the diagram below.

1)Takeout the insulation strip from the upper packing.

2) Attach the insulation strip onto the rear upper side of the

wall sleeve.

3) If anyone would like to improve unit energy efficiency, it

is recommended the change ofoutside grillefor an unit

protection and an addition of a plastic rear grille.(This is

optional.)

TEMPERATURE CONTROL

Set the Thermostat control to the desired

temperature mark 5 (the mid-point is a good

starting position). If the room temperature is not

satisfactory after a reasonable time, adjust the

control to a cooler or warmer setting, as

appropriate.

• VENTILATION

The ventilation lever is locatedto the lower left side

of the unit.

The ventilation lever must be in the CLOSE position in

order to maintain the best cooling conditions.

When fresh air is necessary in the room, set the

ventilation lever to the OPEN position.

The damper is opened and outdoor air is drawn

into the room.

This will reduce the cooling or heating efficiency.

CAUTION

When the air conditioner has been running and is

turned off or set to the fan position, wait at least 3

minutes before resetting to the cooling operation.

Note: A slight heat odor may come from the unit

when first switching to HEAT after the

cooling season is over.

This odor, caused by fine dust particles on

the heater, will disappear quickly.

This is harmless.
